Despite inheriting those great features of the standard thinner, the professional thinner is unique in effectively reducing surface tension of paint layers. Lacquer paints tend to evaporate constantly when drying, causing the paint coating to shrink unevenly, forming a sandpaper like coarse texture. DSPIAE's professional thinner's superb volatility guarantees an extra smooth finish of your paint job, especially helpful when a high gloss, mirror-like finish is required in a large area. Benzene free formula, low odor and low shrinking. Continental USA shipping only. Ground service only.
